Example
When we learn any programming language, the first step is writing a simple program to display "Hello World". So, here is a simple Java program that displays "Hello World" on the screen.

public class HelloWorld {
    public static void main(String[] args) {
        System.out.println("Hello World!");
    }
}

Output

Hello World!
